DETAILED DESCRIPTION OF THE INVENTION

A system 10 in accordance with one embodiment of the disclosure is illustrated in FIG. 1. The system 10 includes a database 12, query engine 14 and an interactive user interface 16. A call center 20 receives and makes calls with a caller/customer 15. During a call, call data is recorded at the call center. The call data is uploaded to the database 12 in real time. The call center 20, database 12 and interface 16 may be provided within the same premises or may be distributed with suitable communications links between the separate components. In addition, the call center itself may be provided in a distributed manner, as is known for call centers.

The call center 20 may include components including an Interactive Voice Response (IVR) system 21, call center agents 22 as well as automated systems 23 for recording touch tone data, such as for survey responses. A transfer center 25 controls the transfer of data from the call center to the database 12. A call may be initiated at the call center 20, either from within the call center 20, such as by a call center agent 22, or from outside of the call center by a caller 15. The term “caller” is used herein to denote persons outside of the call center regardless of whether that person placed or received the call.

A method 100 for analyzing call data is illustrated in the FIG. 2. At step 101, a call is initiated allowing recording of call data to commence (step 102). The recorded call data is transferred to the database 12 in real time (step 103), thereby allowing queries to be executed (step 104) on the most up to date call data.

For each call initiated at the call center 20, a call record 26 is created. The call record 26 has a number of fields for recording call data. In one embodiment, the call record 26 may include fields for a call ID, caller ID, call device ID (e.g., mobile telephone identifier), time and date, call agent, and/or IVR identifier (e.g. if multiple IVR paths are provided by the call center) etc. Specific call fields may include call path exit points, survey data and fields for recording sound files or interactive touch tone data, such as for completing surveys and the like. Additional fields for recording useful call data will be apparent to a person skilled in the art.

The call record 26 has a data and addressing structure compatible with the database 12 that allows for easy transfer of the call record from the call center 20 to the database 12 by the transfer center 25. The call record 26 may be transferred completely or individual fields may be selected from the call record and transferred separately. The transfer center 25 may operate using any suitable transfer protocol, such as via an FTP link, TCP/IP transfer, direct file transfer, or similar. A call record will be initialized with empty fields which may be filled as data for those fields becomes available.

The fields of the call record 26 may be filled in a manner of ways. In one embodiment, a controller of the IVR system 21 enters data into the fields of the call record 26. In one embodiment, the call data may be entered by a call agent 22.

In one embodiment, the call record 26 is uploaded to the database 12 by the transfer center when the call record 26 is created. As the call progresses, call data may be periodically uploaded to the call record 26 in the database 12 by the transfer center 25. For example, data for the caller ID, call agent, and time and date fields may be uploaded as soon as the call is initiated. Other data, such as an IVR path field may be continually updated as a caller progresses through an IVR call path. Sound files and other inputs provided by the caller may also be recorded into the call record as they are provided by the caller and/or call agent. In one embodiment, a call data record may be generated and stored locally in the call center 20 during the call and uploaded to the database 12 once a call is completed. Using any of these methods ensures that call data is uploaded to the database 12 in real-time.

Once data is uploaded to the database 12, it becomes searchable by the query engine 14, thus providing real-time access to call data. Real-time access provides a high degree of functionality.

A method 200 for analyzing call records is illustrated in FIG. 3. A call record 26 is created at step 201. At step 202, data is entered into one or more fields of the call record 26 allowing the call record fields to be transferred to the database 12 (step 203). At step 204, queries are executed on the call records in the database 12.

In one embodiment, a query may identify frequent callers, for example where a caller ID or device ID is identified as making a number of calls above a threshold number in a time period shorter than a threshold time period. A high call frequency may be indicative of a troubled caller, a prank or fraudulent caller, or the like. A troubled caller, such as someone unfamiliar with an IVR system may further be identified as repeatedly exiting an IVR call path before reaching an end point of the call path. A query on the database 12 may identify that a caller, identified by their caller ID, has made multiple attempts at an IVR menu. Such callers may be flagged so that the next time that caller initiates a call, the caller may be transferred to a call agent who can handle the call directly. Thus, a troubled caller may be assisted by a call agent and prank callers may be dealt with appropriately, in particular, by having the call transferred to a higher level call agent, such as a supervisor or manager.

The real-time collection of call data allows easier analysis of call center statistics. Examples of queries that may be performed by the search and query engine 14 on the database 12 include:

ability to generate repeat caller statistics;

ability to perform real-time speech analytics queries as calls come in;

ability to generate top call paths;

average length of call;

authentication rate;

self service percent, i.e. the percentage of callers that are able to satisfactorily complete the call through an IVR menu without call agent assistance.

From the above examples, it will be apparent to a person skilled in the art that queries may be executed on a customer specific level or at any higher macro level that allows groupings of calls and/or callers to be made.

Statistical data generated by performing queries of the type described above allows call center designers to design more efficient and caller-friendly IVR systems, for example by locating problem points in an IVR path where callers terminate the call or seek call agent assistance. This can be vital in situations where a particular IVR application has a short lifespan requiring the need to process a high call rate.

Another application of the search and query engine is in processing survey responses in real-time. Survey responses may be recorded by call agents who enter caller responses directly into call records, by recording touch tone responses of callers, or by determining a path through an IVR menu as well as other methods. Survey data uploaded to the database 12 can be analyzed using database queries to collate statistics on survey answers.

The database 12 may be linked to one or more additional databases 19 for archiving call data. In one embodiment, the database 12 may store 1-2 months of data accessible by the query engine 14, while the archive database 19 stores older call data that may be searched by more specific queries from the query engine 14 to the archive database 19.

Queries may be generated by an operator through the interactive user interface 16. The interactive user interface 16 may be provided on a computer terminal with a suitable display screen. The interface 16 may connect with the query engine 14 via a suitable communications link, which in one embodiment may be an internet link. Queries may be generated using forms on the interface 16 or other standard templates. The interactive user interface 16 may also display query results in a variety of formats. In various embodiments, the interactive user interface allows:

ability to view a graphical image of a dominant IVR call path data at the macro level;

ability to view a graphical image of a customer cross-channel interaction—e.g. within the Web, IVR and Agent;

ability to graphically view exit point statistics, i.e. points at which customers exit the IVR—via hang-up, via agent transfer, etc;

ability to graphically view the success and error rates for all self-service functionality within the IVR;

ability to drill down from the macro level call path view to the customer level to obtain customer specific data;

ability to view customer transaction information for all calls into the IVR during a user-defined period;

ability to link from a customer-level call path view to related survey score information;

ability to link from a customer-level call path view to associated call recordings;

ability to link from a customer-level call path view to speech analytics results;

ability to view trending information on call paths, e.g. most frequently visited, etc.;

ability to graphically identify IVR call path points with high error rates, invalids and time outs;

ability to view summary level information on repeat caller statistics;

ability to drill down to detailed timing information for repeat caller statistics;

ability to trigger internal notifications for client services teams if pre-defined thresholds have been exceeded;

ability to trigger external notifications for external clients if pre-defined thresholds have been exceeded.

For ease of use, the interactive user interface may be configured with a set of standard queries that are selectable by menus or the like. The queries may be categorized with access to different categories being dependent on user permissions. In addition, access to certain call data may be limited based on a user profile and permissions.

In one embodiment depicted in FIG. 4, the call center 20 includes at least one processor 51 operatively associated with at least one memory 52. The memory 52 stores an instruction set 500 executable on the processor 51. Executing the instructions causes the processor 51 to create a call record (step 501), record call data into one or more fields of the call record (step 502) and transfer the call data to the database (step 503).
